3 SYSTEM DESCRIPTION The Coffee Lovers System TM (CLS) is a five stage reverse osmosis drinking water system. Due to the Dual-Pass TM Technology, the system can also be described as having seven (7) virtual stages. The incoming feed water from a cold supply pipe valve is directed through 1/4 tubing and to a 0.5 micron Micro-Tec TM Sediment Pre-filter. This filter is used to remove excessive turbidity, sand, dust, silt etc that may cause the carbon filter to plug up. The next stage of filtration is a 0.5 Carbon Block Pre-filter. This filter is used to remove organics and chlorine from the feed water that can damage the membrane. The next stage of the system are the R.O. membranes. High-rejection Thin Film Composite (TFC) membrane(s) are used in this system. They remove over 98% of most inorganic salts, all micro-organisms and almost all high molecular weight organics in the water. Dual-Pass TM Technology - A post Carbon Filter and a Re-mineralization Cartridge process the RO water twice for proper taste and hardness. Once, when being stored in the tank and a second time on the way to the faucet. TDS Meters - Provides information about membrane performance. Monitors pre- and post- membrane TDS (total dissolved solids) levels. Can be used to determine percent-rejection and performance of the membranes. Pressure Gauge - The pressure gauge will alert you when it is time to change the sediment and the carbon prefilters. Faucet - The sinktop or countertop faucet dispenses the drinking water. To meet plumbing codes, an air-gap is built into the faucet drain water tubes. The air-gap prevents a back siphon of drain water. Automatic Shutoff - When the pressurized storage tank has filled with product water, a pair of pressure switches automatically shuts off feed water flow to the membrane via the input solenoid valve and resumes flow to the membrane when the pressure tank is half emptied. Check Valve - A check valve is installed on the product water outlet of the RO housing. The check valve prevents a backward flow of product water from the pressurzied storage tank to the membrane. A backward flow could rupture the membrane. Electric Booster Pump - Booster Pump provides elevated and consistent membrane pressure for more efficient operation. Electric Permeate Pump - Most ordinary RO drinking water systems needlessly waste huge quantities of water. SpectraPure s drinking water systems with Permeate Pump provide a solution. The Permeate Pump can reduce waste water more than 300% compared to conventional RO drinking water systems. Additonal advantages include longer filter and membrane life, greatly improved water quality, tank refills in half the time, greater holding tank capacity, and extended low line pressure operation. Re-Mineralization Cartridge - Reintroduces certain minerals to the RO water to provide a ph-balanced and better-tasting water especially suited for brewing coffee and tea. Sump Kit (Optional) - An optional sump kit can be added to the CLS System enabling you to fill an open reservoir with pure water for aquarium, hydroponics or other uses. TDS Kit (optional) - Adjust your TDS to produce Gold Cup Standard water. U.V. Sterilizer Light (Optional) - Add an optional Sterilizer Light to eliminate bacteria. 3

5 PREPARATION 1. Determine an appropriate location for the CLS Water System, Bladder Tank, Feed Water Connection, Drain Saddle. 2. TOOLS RECOMMENDED FOR INSTALLATION: - 7/8 or 1/2 Hole Saw Bit for Faucet Opening (depends on faucet used - Round Knock out Punch for Stainless Sinks, 7/8 & 1/2 - Adjustable Wrench - Sharp Knife - Open End Wrench - Phillips Screw Driver - Needle Nose Pliers- Adjustable Pliers - Electric Drill MOUNTING SYSTEMS INSTALLATION STEP 1. Determine best location for the RO system to be mounted to allow for future system maintenance. When mounting on dry wall, use anchors to support the weight. To Mount: screw directly through poly board onto wall. Leave enough space and tubing so that you can pull the system out for maintenance. TANK INSTALLATION STEP 1. Position tank in desired location. Stand it upright. STEP 2. Connect the Blue Tubing that leads out of the Dual Pass, marked TANK, Shown on page 6, to the ball valve. NOTE: The storage tank is pressurized with air at the factory to 6 psi with the tank totally drained. Over a period of time, air may leak out causing the delivery rate of the stored water to decrease. If this occurs, verify correct tank pressure using a low pressure air gauge on the tire valve stem located on the bottom, or near the flange at the top of the tank with tank completely empty of water. 5

7 FEED WATER VALVE INSTALLATION STEP 1. Follow the cold water line from shut-off valve to the existing faucet and unscrew the threaded connection. STEP 2. Insert feed supply valve between cold water line and existing connection. STEP 3. Follow the assembly sequence shown for attaching valve to the existing cold water line. STEP 4. Connect Black line from RO system as shown in Fig 1. a. Remove the 1/2 Compression Nut from Valve body. Be carefull not to loose the plastic or brass Insert and the Conical Compression Sleeve. b. Insert the 1/4 Black Tubing into the Compression Nut with the threads towards the end of the tube. c. Slip the Conical Compression Sleeve onto the Black Tube with the long slope pointing toward the end of the tube. d. Place the Insert into the end of the Black Tubing. Make sure you push the insert in all the way. e. Tighten Compression Nut back on the Valve body. STEP 5. When installation of the valve is complete, check for leaks as follows: a. Close Feed Supply Valve that you just installed. b. Open cold water supply valve and check for leaks around feed supply valve fittings. Tighten if necessary. Note: To be certain of the cold line; turn on the hot water, allow water to run until pipe becomes warm. Then attach fitting to the cold water line. If you run hot water through your system it will damage the membrane. FEED VALVE INSTALL ON COLD WATER LINE FIGURE 1: FEED SUPPLY INSTALLATION 7

8 PROCEDURE FOR MEASURING WASTE TO PRODUCT WATER RATIO This procedure will assure you of maximum life and reliability of your SpectraPure System. Failure to perform this procedure can permanently damage the membrane and will void the pro-rated Membrane Warranty. In order to maximize the life of your SpectraPure RO Membrane, you may need to adjust the ratio of the concentrate to purified water. If not enough concentrate is allowed to flow past the membrane during operation, the impurities will precipitate out on the membrane surface, clogging the RO Membrane. To keep this from happening, the Concentrate to Purified Water Ratio must be checked and adjusted in order to compensate for pressure and temperature variations that exist in all water supplies. The flow rate of the concentrate must be a minimum of 3X the product flow rate. 3X to 5X is an acceptable concentrate flow rate. Procedure: 1. Locate the Yellow waste line. Direct the waste line into a sink drain. 2. Locate the Blue product line. (LINE MARKED FAUCET ON PAGE 6) Direct the product line into a sink drain. 3. Turn on the Feed Supply Valve and let the system run for 20 min. 4. Collect product water from the blue line into a measuring cup for one minute. Measure the collected amount in milli-liters. (30 ml = 1 oz) Do the same with the waste water. WASTE IN MILLILITERS ML DIVIDED BY PRODUCT IN MILLILITERS ML The resultant is the Concentrate to Product Ratio (Although not needed in this procedure, the daily product flow rate in Gallons per Day (GPD) can be calculated to be equal to the product flow rate times 0.38 ). 5. If ratio is less than 3:1= Remove Flow Restrictor as shown on page 8-9 and cut 1 off. 6. Re-measure your ratio and repeat proceedure untill you acheive a 3/1 ratio. 7. If ratio is greater than 5:1, flow restrictor requires replacement (Please contact SpectraPure Inc for a longer FR). YOU HAVE FINALLY SET THE SYSTEM UP. NOW CONTINUE TO PAGE 9 FOR START-UP PROCEDURES... FLOW RESTRICTOR REMOVAL, ADJUSTMENT AND REPLACEMENT 1. Locate the yellow concentrate tubing. Remove the tubing from its push-fitting at the membrane as follows: a.) Firmly depress and hold the push-fitting collar down with your thumbnail. b.) While the push-fitting collar is depressed, pull the tubing straight out of the push-fitting. Once the tubing is removed, release the collar. 2. Carefully remove the flow restrictor assembly, now visible as a plastic insert In the end of the yellow tubing. You may use an object such as a dull knife to help pry the flow restrictor insert from the end of the tubing. The entire flow restrictor (consisting of the insert collar and thin capillary tubing) may then be gently extracted. Note: Take care not to crush or otherwise damage the delicate capillary tubing. 8

9 4. Using a NEW single-edge razor blade, carefully measure and then cut the flow restrictor. 5. Re-insert the flow restrictor assembly into the yellow tubing and firmly re-seat the insert into the end of the yellow tubing by carefully pressing on the insert with your thumbnail. Care should be taken not to crush or other-wise damage the end of the capillary tubing protruding from the end of the insert. 6. Re-insert the yellow tubing into its push-fitting in the RO membrane as follows: a.) Moisten the O-ring seal inside the concentrate outlet fitting by dripping a few drops of clean water into the fitting. b.) Grasp the yellow tubing near the flow restrictor end, and insert the tubing into the push-fitting. Push the tubing into the fitting until resistance is felt, approximately 1/2 inch (12.7 mm). The tubing is now resting on the O-ring seal inside the fitting. c.) Firmly push the tubing approximately an additional 1/4 inch (6.35 mm) further into the fitting to completely seat the line into the fitting and O-ring seal. 7. Turn on the system water supply and check for leaks prior to further use or testing. If a leak is observed, you may not have pushed the yellow tubing into the push-fitting far enough to seal the tubing against the O-ring. Turn off the system water supply and re-seat the tubing as described above. Flow Restrictor Assembly YELLOW TUBING FLOW RESTRICTOR START-UP PROCEDURES (AFTER CONNECTING LINES TO TANK AND ADJUSTING RESTRICTOR) 1. Connect the Blue Line to your faucet or Espresso Machine and the Waste Line (Yellow) to the Drain Saddle as shown on page If you have the UV Light: Install lamp inside stainless steel housing, making sure you do not cross thread the end fittings, and connect the transformer to the open end. 3. Slowly open the Feed Water Adapter. 4. Allow the tank to fill for at least 2 hours. Drain the tank fully and then allow the tank to refill all the way. 5. When the tank is fully pressurized, the system should automatically shut off. 6. CHECK FOR LEAKS. DO NOT LEAVE SYSTEM ALONE UNLESS YOU ARE CERTAIN THERE ARE NO LEAKS. NOTE: It is important that air is purged from system during initial operation. To do this, orient the RO unit with the product (permeate) and reject (brine) water ports pointing upwards. (Round end of RO membrane housing is up, pre-filter housings are horizontal). Allow a minimum of 15 minutes operation with this orientation. Note: Never run hot water (>100 F) through the system. 9

10 DRAIN SADDLE INSTALLATION Refer to Figure 1 and determine the location for the drain saddle assembly and drain hole. It must be located above the P trap ( U shaped bend in drain pipe) on the sink side of the drain pipe. Place the half of the drain saddle with threaded nipple at a pre-determined location. Slide a pencil through the plastic nipple and make a mark on the drain pipe. Use a small punch and indent a start position to prevent the drill bit from wandering. Drill a 3/8 hole in the drain pipe through the mark on one side only, do not drill through both sides of the drain pipe. Clean any loose shavings from around the hole. Refer to Figure 2 showing the drain saddle assembly sequence. Press nuts in back half of drain saddle assembly. Align the front half of the drain saddle by inserting a pencil through the plastic nipple and the newly drilled hole in the drain pipe. Install the back half of the drain saddle and clamp assembly to drain pipe by screwing in the mounting bolts until snug.

11 MAINTENANCE PROCEDURES For maximum contaminant removal and long membrane life, the sediment and carbon pre-filters should be changed at 6-month intervals. If your water contains a great deal of sediment or chlorine, the pre-filters might have to be changed at more frequent intervals to maintain an adequate production rate. Sediment pre-filter and Carbon block pre-filter Replacement Maintenance Regime: Materials Needed: 15-20% drop in pressure OR at least once in 6 months OR when chlorine breakthrough occurs. 0.5 micron micro-tec sediment pre-filter, 0.5 micron carbon block pre-filter, filter wrench. Procedure: 1. Shut off feed supply valve and wait until pressure is relieved. 2. Remove the filter housings from their caps by unscrewing them clockwise as viewed from top or side. A filter wrench may be needed. 3. Discard old filters. 4. Thoroughly wash out the housings with hot soapy water to which a few teaspoons of household bleach have been added, and rinse well with clean hot water. 5. Install the new sediment pre-filter in the left most housing, check to be sure that the O-ring is positioned in its groove and hand tighten housing. 6. Install carbon block pre-filter in appropriate housing making sure, O-ring and black gaskets are in place. Hand tighten housing. 7. Turn feed supply valve ON and check for leaks. (See Start-Up proceedures ). - RO Membrane Replacement - Maintenance Regime: As needed (Refer to procedure for testing membrane quality). Materials Needed: Replacement TFC membrane, pliers. NOTE: If 180 GPD System, then (2) 90 GPD membranes are required. Procedure: 1. Shut off feed supply valve to the DWS System and wait until pressure is relieved from the housing. 2. Next, remove the short 1/4 black tubing from the input elbow of the lower membrane and lift the membrane housing from the clips. 3. Unscrew the RO housing lid counterclockwise from base. 4. With a pair of pliers, grasp the membrane stem and pull the membrane from the housing. 5. Wash housing with soapy water and rinse thorougly with hot clean water. 6. Insert new membrane into the housing, with the o-ring end first. The o-ringed tube must fit into the recess at the bottom of the RO housing. When the membrane is aligned with the hole, push the membrane into the hole until it bottoms out. 7. Re-install housing O-ring on the housing rim and carefully screw the lid back on to the base. 8. Reconnect the 1/4 black tubing to the input elbow of the membrane. 9. Disconnect the yellow drain line from the membrane housing and remove the flow restrictor from the end of the yellow tubing and reconnect the yellow tubing without the flow restrictor to the membrane housing. 10. Turn on feed supply valve. Flush the membrane and membrane housings for 10 minutes. 11. Turn off the water supply to the System. Remove the yellow drain line from the membrane housing and replace the flow restrictor in the yellow line. 12. Reconnect the yellow drain line with the flow restrictor to the membrane housing, turn water supply on and check for leaks. 13. Check ratio of waste water to product water. It should be at least 3: 1. If it is not 3:1, check the flow restrictor for particle plugging or adjust ratio to 3:1. (See Start-Up proceedures). 11

12 - Post-filters Replacement - MAINTENANCE continued Maintenance Regime: At least once in 12 months or whenever odor or bad taste occurs. Materials Needed: Replacement Carbon Post-Flter. Procedure: 1. Turn off feed supply valve and tank shut-off valve. 2. Remove the filter housing from its cap by unscrewing it clockwise as viewed from the top or side. 3. Discard old filter. 4. Thoroughly wash out the housing with hot soapy water to which a few teaspoons of household bleach have been added, and rinse well with clean hot water. 5. Install the new post-filter. 6. Turn on both tank shut-off valve and feed supply valve. (Check for leaks) - Re-Mineralization Cartridge Replacement - Maintenance Regime: At least once in 12 months or whenever more than 50% of the minerals are exhausted. Materials Needed: Replacement StablePure TM Re-Mineralization Cartridge Procedure: 1. Turn off feed supply valve and tank shut-off valve. 2. Remove the filter housing from its cap by unscrewing it clockwise as viewed from the top or side. 3. Discard old cartridge. 4. Thoroughly wash out the housing with hot soapy water to which a few teaspoons of household bleach have been added, and rinse well with clean hot water. 5. Install the new cartridge. 6. Turn on both tank shut-off valve and feed supply valve. (Check for leaks) - UV Light - The life span of the U.V. Ligh is approx 7,000 hours of usage. Replace Bulb when life is exhausted. - SANITIZING THE DRINKING WATER SYSTEMS - Sanitizing is recommended at least once every year or if water smells (or tastes) bad even after a post carbon filter replacement. A convenient time for sanitization is during a filter change-out. IT IS IMPORTANT THAT YOU HAVE CLEAN HANDS WHILE HANDLING INNER PARTS OF THE SYSTEM. 1. Be sure water supply to the RO system is turned off, and the dispenser faucet is open. This will completely drain the pressure tank. 2. Remove the post carbon filter and the remineralization filter from the system. 3. Put oz. of household bleach in the right filter housing and fill it half-way with tap water. 4. Next, close the dispenser faucet (put lever in DOWN position). 5. Open the feed supply valve. 6. Allow 10 minutes for the bleach solution to flow through the system and into the storage tank. 7. Open dispenser faucet and keep the lever in the UP position till some bleach solution is dispensed through the faucet. IMMEDIATELY close the faucet as soon as the bleach solution is detected. This will sterilize the faucet and the line going to the faucet. 12

13 MAINTENANCE continued 8. Let the system sit for 2 hours. 9. Open the dispenser faucet to drain bleach solution from the pressure tank as completely as possible and then close the faucet. 10. Open the feed supply valve fully. 11. Allow the tank to fill until pressure gauge reaches at least 40 psi. Then open the dispenser faucet and flush system until all bleach solution has been dispensed from the system. 12. Close the feed supply valve. 13. Remove post-filter housings from the system and then rinse them with tap water and drain completely. 14. Install new post-carbon and remineralization filters and hand tighten the housings. 15. Open the feed supply valve and check for leaks. This completes the procedure. NOTE: Do not use filter wrench to tighten housings. Over-tightening will damage housings and void your warranty. CALCULATING EXPECTED GPD/LPD FROM THE MEMBRANE Membranes produce the rated gallons per day (GPD) at 60 psi (4.1 bars) operating pressure, 77 F (25 C) operating temperature and 500 ppm total dissolved solids. Membrane output gallons per day (GPD) depends on operating pressure, water temperature and the ppm TDS in the feed water. Expected GPD = Rated GPD PCF TCF OCF where PCF is the pressure correction factor, TCF is the temperature correction factor and OCF is the osmotic correction factor. 1. Calculation of PCF:The output GPD from the membrane are directly proportional to the applied pressure. Note: The membrane is rated to produce the rated GPD at 60 psi. For any pressure other than 60 psi the output GPD is multipled by the PCF (Pressure correction factor). PCF = Pressure available (in psi) Calculation of TCF: The output GPD also decreases with decrease in temperature. This is because the water viscosity increases with decrease in water temperature. The GPD increases by approximately 3% for every C rise in temperature. (Refer to the following table for TCF values). F ( C) TCF F ( C) TCF F ( C) TCF 41.0 (5) (15) (25) (6) (16) (26) (7) (17) (27) (8) (18) (28) (9) (19) (29) (10) (20) (30) (11) (21) (31) (12) (22) (32) (13) (23) (33) (14) (24) (34) Table 1: Temperature Correction Factor (TCF 13

14 3. Calculation of OCF:The output GPD of the system decreases with an increase in ppm TDS of tap water. This is because the osmotic presssure increases with increase in ppm TDS, and the increased osmotic pressure reduces the net driving force for pure water passage through the membrane. The osmotic pressure is approximately 1 psi for every 100 ppm TDS. Note: Generally speaking, the effect of osmotic pressure can be neglected for most tap water supplies and the OCF can be assumed to be 1. Example: What is the expected GPD from a 50 GPD DWS system at 40 psi pressure and 60 F water temperature? PCF = = TCF = (from Table 1) OCF = 1 Expected GPD = = 25.1 GPD Important Note: This calculation makes the assumption that purified water from the system is going into an open tank or reservoir. Actual System GPD will be lower for the DWS System because of the back pressure exerted by the pressurized storage tank. Addition of the Permeate Pump Retrofit-Kit (PPRFK-DW, Part #: KT ) eliminates the back pressure and operates your DWS System as if the product water were going into a open tank. - Recharging the bladder tank - If the storage capacity of the tank is diminished significantly it is likely that the tank has lost its air charge. Recharging the bladder tank will restore its capacity. 1. Put the dispenser faucet in the open position (lever in up position). Leave the faucet in the open position untill the procedure is completed. 2. Drain as much water as possible from the tank. 3. Hook up an air pump to the Schrader (tire) valve on the pressure tank and start pumping air into the tank. 4. Expel all the water from the tank. 5. Continue pumping air into the tank until the pressure reads 6 psi. 6. This completes the procedure. Note: Should this procedure fail to restore the capacity of the tank, it is very likely that the bladder in the tank is ruptured and the tank needs replacement. Troubleshooting Guide Continued on Next Page. 14

15 TESTING THE QUALTIY OF THE MEMBRANE The performance of a RO membrane is measured in terms of its rejection characteristics. Note:Test the quality of the membrane once every 6 months. Method 1: Using a test kit The rejection of the membrane is measured using the following procedure. 1. Turn the right-angled ball valve on the top of the pressure tank to the OFF position. Flip the faucet lever into the UP position. 2. Measure tap water conductivity* (Call it X). 3. Run the system for 30 minutes. 4. Rinse test instrument cell 2-3 times with RO water. 5. Measure RO water conductivity* (Call it Y). 6. Subtract RO water conductivity* from tap water conductivity* (X - Y). 7. Divide this quantity by tap water conductivity* (X - Y) X. 8. Rejection = [(X - Y) X ] Put the faucet lever back to the DOWN position and then turn the right-angled ball valve to the ON position. * Conductivity in the above procedure could be replaced by hardness, alkalinity, nitrate, phosphate, silica etc. (measured in ppm or mg/l). These test kits are commonly available at aquarium stores. Example: Calculation of Rejection of the RO Membrane. 1. Tap water hardness = 150 ppm (X). 2. RO water hardness = 7 ppm (Y). 3. X - Y = 143 ppm. 4. (X - Y) X = = Rejection = [ ( X - Y) X ] 100 = = 95.3 Membrane Hardness Rejection = 95.3 % Þ Membrane OK. Depending on your tap water chemistry, the rejection characteristics of the membrane may vary significantly. Following tips will ensure a good membrane life. They are: Tips for good membrane life 1. Replacement of 0.5 micron Micro-Tec TM sediment filter once every 6 months OR when the pressure indicated by the pressure gauge drops by 15-20% (whatever happens first). This will prevent membrane fouling due to silt or sediment depositing on the membrane. 2. Replacement of 0.5 micron carbon block filter at least once every 6 months OR when the pressure indicated by the pressure gauge drops 15-20% (whatever happens first) OR when chlorine breakthrough occurs *. This will ensure good membrane life and prevent membrane from chlorine damage. 3. Membrane should not be operated at lower than 4:1 waste water to product water ratios. If you have a lower ratio, change the length of the flow restrictor to adjust to at least 4:1. 4. Running reverse osmosis systems on softened feed water reduces the chances of membrane fouling. * Method to check for chlorine breakthrough : Detection of chlorine levels > 0.1 ppm in brine (1/4 yellow waste water line).
